First the star layered the jacket over a black tee, matching jeans and Charlotte Olympia leopard print flats. Then, she opted to pair it with a white T-shirt, black jeans, neutral pumps and a printed scarf.
Both looks were ultra chic (like we'd expect anything less from Rosie!) and ideal for the upcoming fall season. So we tracked down the coat's designer, Anine Bing, to chat about the best way to pull off the look.
"I love the way Rosie wears my studded leather jacket. She captures the balance between rock n' roll and elegance perfectly," Anine shares. "She has that ‘model off duty look' that I always have in mind when I'm designing my line."
So how can you copy the blond bombshell's look?
"It's all about finding the balance between soft and hard and matching the leather with other soft fabrics," Anine explains. For example, she recommends pairing it with a floral print skirt, or leather ankle boots.
Lastly, "the fit and the quality of the leather is the most important factors when picking out your leather jacket," she says. So be sure you give it a solid store-based test run before buying.
